5.  Solubility in Caustic Soda Solution.   -20 e.e. of the alcohol are
mixed in a 100 c.c. graduated cylinder with 40 c.c. of 32% sodium hydroxide
solution (D 1-35) and left for an hour, the volume; of the Hunting insoluble
portion being noted.

6.  Determination of the Acetone.-Messinger's method is used, the
following solutions being required :

(a) 80 grams of caustic soda (puriss.), free from nitrites, per litre.1
(6) Approximately 10% sulphuric acid solution, 100 grams of the pure

cone, acid being made up to a litre ;  10 c.c. of this solution should more

than neutralise 10 c.c. of (a],

(c) Approximately N/5-iouine solution, obtained by dissolving about

1 10 c.c. of this solution, treated with 0-1-0-2 gram of potassium iodide ami acidified,
with hydrochloric acid, should yield n,o free iodine. oxalic acid.                                            ^'--;'
